A chilling photo has circulated Twitter since Aug. 9; the photo features an Islamic State flag held in front of the White House with the caption, “We are in your state. We are in your cities. We are in your streets.” Connected to that photo is an image of a handwritten note written in Arabic that translates to, “Soldiers of the Islamic State of Iraq and Syria will pass from here soon.” The note is dated June 20, 2014.

The Secret Service is taking the potential security breach seriously.

"We have an intelligence division whose mission is to assess information that we receive every day for dangerousness or potential threat level. We are aware of the image and will take the necessary and appropriate follow-up steps," said Ed Donovan, Secret Service spokesman.
